SYLVANUS I). LOOKE, OF HOOSIGK FALLS, NE'W YORK.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 233,781, dated October 26, 1880.

Application filed September 23, 1880.

To all whom it may concern:

Be it known that I, SYLVANUS 1). LOOKE, of Hoosick Falls, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

My invention relates to that type of harvesters known as the Marsh, and now extensively used in connection with automatic and hand binding attachments. These have an endless canvas elevator, which lifts the grain from the platform to the binding-table, and of late years the most advantageous construction has been considered one in which the elevator is double-that is, in which the grain, as it is carried up by the elevator-apron, is pressed upon by a parallel superimposed endless apron, either idle or positively driven, preferably the latter. Heretofore the drums upon which these upper and lower elevator-aprons run have been supported by standards at both front and rear of the machine. Consequently it has been necessary to make the machine of such a transerse width as to allow the passage between these standards of the longest grain that it may be required to harvest.

The object of my invention is to reduce the size of such machines and the attendant dead weight and to bring them more in proportion with their effective energy; and it consists in overhanging the upper elevator-apron from the front of the machine, leaving a clear passage way between its rear and the rear of the underlying apron, whereby the transverse width of the machine may be reduced to about twothirds of the length of the longest grain to be harvested.

It further consists in the various combinations and details of construction hereinafter pointed out and claimed.

In the drawings, Figure l is a perspective view of so much of a harvester embodying my invention as is sufficient to a proper comprehension thereof. Fig. 2 is a vertical section longitudinally of the harvester. Fig. 3 is an end elevation from the stubble side of the ma chine, and Figs. 4 and 5 are details.

A is the grain-platform, which may be supplied with any suitable means for moving the grain, such as a canvas apron or the rake de- (No model.)

scribed in Letters Patent N 0. 214,929, granted April 29, 1879, to myself and Egbert Bowhay, as joint inventors. The rear rail of this plat-- form is flush with or slightly below the effective surface of the rake, thatgrain may project be yond it without being obstructed in its movement.

B is the elevator-frame, resembling in general the ordinary elevator-frame used in this class of harvesters. Journaled in this frame, respectively at top and bottom thereof, are gudgeons b 1), bearing drums of such diameter as to bring the upper surface of the main elevator-apron G,which they support, even with or slightly above the rear rail, 0, of said frame so that it may receive long grain from the platform-rake and carry it up and deliver it over the top of the frame with its heads still projecting behind the machine.

Firmly bolted to the front timbers of the elevator-frame at their apex, and serving, by means ofits flaring legs, to bind them together, is a casting, D, having two bearings, cl (1, the first of which forms the front bearing of the upper drum of the main elevator-apron and the Second the front bearing of the upper drum of the supplementary apron, and both of which are elongated to steady their respective drums, and particularly the overlying one. At its top the casting is formed with a bracket, 6, to which is bolted the front end of a bar, E, supporting at its other end, by means of a strap, 6, the upper end of the rear bar, F, of the supplementary apron-frame. The bar E will also, when the harvester is used with an automatic binding attachment, serve as a support for the upper trackway for the back-andforth adj ustment of the binding table and mechanism.

The bearings of the gudgeons f f of the supplementary apron-drums are, as will be understood, respectively in the casting D and in the front rail or bar, a, of the elevatorframe at the front of the machine and in either end of the bar F at the rear of the machine, and the drums support the apron G in such manner that its lower surface is flush with or below the lower edge of said bar.

Immediately in front of the elevator-frame, and in such position as to afford a support for the reel, two vertical posts or standards, H

H, rise from the ground-sills of the harvester. These are connected near the top by a tiepiece, h, and may be otherwise braced.

To the post H,just above the front rail of the elevator, is bolted a bracket-casting, I, having side flanges, i, on its horizontal arm, which form a socket to receive and brace the front end of a bar K, further secured therein by bolts. This bar supports at its rear end, by means of a strap, it, the lower end of the bar F, and to prevent it from sagging under the weight of the supplementary frame and apron, which is by this construction mainly thrown upon it, it is connected by a stay-rod,

L, from a point near its rear end, with the upper part of the post H. As a further safeguard the stay-rod may be furnished with a turn-buckle, whereby it can be shortened or lengthened to. compensate for any warpin g or springing of the wood-work.

Instead of the two posts H H, the single post H, strongly braced, will ordinarily prove su'fficient, and instead of a single stay-rod leading therefrom to the lower bar, K, two or more stay-rods may be employed, connecting the post with both the upper and the lower bar, and, if desirable, with the rear bar, of the supplementary frame about midway of its length.

The lower end of the supplementary apronframe may also be so mounted in slots in the strap I. and in the front bar, 0, of the elevator-frame as to rise and fall with the varying depth of the stream of grain passing beneath. Such a construction, it is obvious, will ordinarily require that it shall have both a front and a rear frame-bar independent of the frame-bars of the elevator-frame, as in the floating aprons now used.

In order that both elevator-aprons may be positively driven, the upper gudgeons, I) and f, are prolonged beyond their front bearings to receive intermeshing pinions, to which power may be communicated from any driven part of the harvester.

I claim as my inventiou '1. In a harvester, the combination, with a main or underlying endless elevator-apron, of a supplemental upper endless apron'overhanging from the front of the'machine, so as to leave a free passage-way at the rear for project-ing grain.

2. The combination, in a harvester-elevator, of two positively-driven parallel aprons, one above the other, and a frame overhung from the front of the machine, in which the rear gudgeous of the upper apron-drums are journaled.

3. The combination, in a harvester-elevator, of a main or lower endless elevator-apron, a supplementary overhung endless apron, a frame overhung from the front of the machine, in which the drums of said upper apron are journaled, and a stay rod or rods connecting the rear part of said frame with a post or standard at the front of the elevator.

4. The combination, in a harvester, of the upper and under endless elevator-aprons, the bar F, in which the rear gudgeons ot' the upper apron-dru ms are journaled, the bars E and K, supporting said rear bar from the front of the machine, the post H, and the stay-rod extending from said post to a point near the rear I end of the bar K, substantially as described.

5'. The combination, with the overhung upper elevator-apron, of the bar E, serving as a support both for the upper end of said apronframe and for a trackway to an adjustable self-binding attachment, substantially as described.

6. The casting D, formed with flaring feet to tie the apex of the elevator-frame and with the elongated bearings for the journals of the upper drums of the main and supplemental aprons, as and for the purpose described.
